SE97B
DDR memory module temp sensor with integrated SPD
Up to eight memory devices can be connected on a single I
2
C-bus. Each one is given a
3-bit on the hardware selectable address (A2, A1, A0) inputs. The device only responds
when the 4-bit fixed and hardware selectable bits are matched. The 8th bit is the
read/write bit. This bit is set to 1 or 0 for read and write protection, respectively.
The corresponding device acknowledges during the ninth bit time when there is a match
on the 7-bit address.
The device does not acknowledge when there is no match on the 7-bit address or when
the device is already in permanent write protection mode and is programmed with any
write protection instructions (i.e., PWP, RWP, CWP).
 
 
7.10.2.1   Permanent Write Protection (PWP)
If the software write-protection has been set with the PWP instruction, the first 128 bytes
of the memory are permanently write-protected. This write-protection cannot be cleared
by any instruction, or by power-cycling the device. Also, once the PWP instruction has
been successfully executed, the device no longer acknowledges any instruction (with 4-bit
fixed address of 0110b) to access the write-protection settings.
